Yonder Alonso is a loss, but they did address the correct need and though he hit well in his 2011 cup of coffee, Alonso's minor league performances suggest that he's a bit overhyped. Among hitters, the Reds actually have a pretty decent field of second-tier prospects.
I love it when people look at numbers without context. He was injured, had his hamate bone removed and probably has just now got his power back. I love the trade, but IMO, the Padres got a lot more interesting.
